| Research Abstract |
The research has been undertaken to analyze quantitatively the shape, dimension, and arrangement of wood structure which is consist of elements visible with nacked eye and microscope. The properties and structure of wood-based baords and pulp were also investigated in relation to the shape and configuration of the raw material. Additionally viaual images of wooden interior of residence were analyzed in a psychological aspect. Various image analyzing methods were used in the studies.
1. Analyses of naked eye visible objects: (1) Quantitative analysis of shapes of round wood in order to decide most suitable sawing pattern for getting largest yield. (2) Quantiataive analysis of knots appering on conifer lumbers for distinguishing knot area and measuring three-dimensional grain angle surrounding knots by use of image processing methods. (3) Quantitative analysis of visual patterns appearing on wooden panels, and ratio of wood parts used in interior space in connection with the psychological images.
2. Analyses of microscopically visible elements: (1) Stereo-analysis of hard-wood fibers in relation to elomgation growth of tress: quantitative analysis of arrangement of hard-wood tissues byoptical Fourier transformation. (2) Determination of contribution of individual wood tissues and cells on swelling anisotropy of wood in water and organic liquids by analyzing the optical microscopic images.
3. Wooden raw materials in morphological aspects: (1) Sudies on effects of particle geometry and compaction ratio on properties of low-density particle board; effects of fiber shape and configuration on fiber alignment and properties of oriented medium density fiber-boards. (2) Quantitative evaluation of network structure of pulp sheets for estimating characterization of pulp; morphological analysis of relationbetween fibers and pigments in filler loaded sheets.
